        $docx = new CreateDocx();
        $docx->embedHTML($html, ['useHTMLExtended' => true]);

The bug is line 6436 of CreateDocx.php:

The str_replace for PHPDOCX_HTML_EQUATION_1 is also matching PHPDOCX_HTML_EQUATION11 and PHPDOCX_HTML_EQUAITON12 and so on. 

I fixed it by adding a non-numerical suffix to the key, so that the searched for string is now "PHPDOCX_HTML_EQUATION_1_".

Lines 6267/8:

$html = str_replace($equation, 'PHPDOCX_HTML_EQUATION_'.$i_mathml.'_', $html);
$nodesMathEquation['PHPDOCX_HTML_EQUATION_'.$i_mathml.'_'] = $equation;

Thanks for your feedback. The same change has been added in the testing branch to be included in the stable release.

As you details, it only happens in Premium licenses with HTML Extended set as true when the same HTML to be imported includes more than 10 equations.
